Uptake of strontium-90 onto silicone antimonate composites

Ion exchange experiments for the uptake of carrier free Sr-90 radioisotope by silicone antimonate composites having a wide range of Si/Sb molar ratio i.e. 0.18 to 2.72 were carried out. The results for various silicone antimo nate composites in the form of kinetics and distribution coefficients showe d that the removal of Sr-90 in the same chemical environment was directly p roportional to the amount of antimony present in the composites. The select ivity sequence for the removal of Sr-90 nuclide in various composites was i n order. All the experiments were carried out in deionized water at room te mperature.
